I just built the following kit:
Although this is supposed to be a quad channel configuration (4x16GB sticks) that should provide a memory bandwidth of around 100GB/s, the measured bandwidth of my memory is around 40GB/s - as if it is a dual channel.
I have setup my sticks as indicated by Asus, i.e. in A1, B1, C1, D1 slots.
Yet, I just came across this video that suggests that in order to get the quad channel performance you should put them in A2B2C2D2 slots.
Obviously it for another ASUS motherboard but I am just wondering if ASUS have made a mess of their manual on ROG Zenith II Extreme and that I should try moving to #2 slots from #1.
Has anyone here noticed this issue?
If this is not the issue, then why the bandwidth is so low?
Last but not least, with my memory, I was expecting to get a very decent latency, yet my scores are awful.
I have uploaded some screenshots here
I have set my memory setting in the BIOS to auto (other than choosing the frequency to 3600).
Should I add the setting manually?
Thank you for your help.
- CPU: AMD Ryzen Threadripper 3960X
- Motherboard: Asus ROG Zenith II Extreme
- Memory: G.Skill F4–3600C16Q-64GTZRC (CAS 16 i.e. CAS to Freq Ratio: 0.44 — with estimated latency of 8.89 nanoseconds)
- HDD: 2 x Samsung 980 PRO NVMe on RAID 0
